'X' covers 300 km is 'a' hours and 'Y' covers 'd' km in
'b' hours. Find a:b Statement I: d = 500 Statement II: Speed of both is same. The question consists of two statements numbered “I and II” given below it. You have to decide whether the data provided in the statements are sufficient to answer the question.Solution
ATQ, Statement I: d = 500 We don't know speed of both. So, data in statement I alone is not sufficient to answer the question. Statement II: Since, speed of both is same but distance traveled by 'Y' is not known. So, data in statement II alone is not sufficient to answer the question. Combining statement I and II: 300/a = 500/b Or, a:b = 3:5 So, The data in both statements I and II together are necessary to answer the question.
